No sensor displayed during New Thing creation step

Hi guys,

I'm working on IoT internal project.

I create a device in IoT service and try now to new create a "new thing" in app Thing modeler of IoT AE.

Unfortunatly when I try to configure the connectivity after having fill the "Provider" field, I cannot see the sensor I previously defined in my IoT service.

I checked in "Data Ingestion error Log" tile and got the following messages on screenshot:

"Failed at device mapping"

Thanks in advance for you help

Regards/

    There are 3 types of connections between iot service and iot ae:

    1. meta-data is sent via Kafka from iot service on device model changes to iot ae
    2. data is sent via Kafka from iot service on new measurements coming in to iot ae and a mapping has been created between sensor and thing
    3. commands are sent via http rest calls from iot ae on command api being called to iot service and a mapping has been created

    The data ingestion error log is only for data (e.g. temperature: 15.0°), not for meta-data (e.g. sensor types, sensors, capabilities). So the fact, that you do not see the sensor meta-data points at a problem with connection type 1 from the above list.

    For the first 2 of the above to work you have to have opened a ticket on the component BC-NEO-IOT-SVC to request a connection between an iot service instance id and an iot ae tenant id (same as the sub-account id in cloud platform cloud foundry). I would check this first in your case.

    For the 3rd one to work you have to put iot service credentials into iot ae with the following apis: https://help.sap.com/viewer/350cb3262cb8496b9f5e9e8b039b52db/latest/en-US/75efcd5109ea43acbe7bf7dccb628058.html?q=target%20value .
